According to investment bank Renaissance Capital, an Iran freed of economic sanctions would prove the final frontier for global equity investors, Bloomberg has reported. “The past 10 years have seen global investors reach into previously untapped markets, from local currency corporate bonds in emerging markets to equities in frontier markets,” London-based chief economist, Charles Robertson, wrote in a March 11 report. “We believe Iran would represent the last such opportunity globally.” Iran’s stock market surged more than 130 percent in 2013 and has a total market capitalisation of $170bn, Robertson wrote. “Many on the ground appear to believe there is a good chance” for the country to open for investment within the next 18 months, he said.
